Fish farming

Energy saving in fish farming

R&R Systems has developed an energy system to extract heat from effluent (manure) for the fish farming sector. Combined with Power Profit Solar Panels or Energy Collectors on the roof, this system provides a fully sustainable heating solution for the water in the breeding tanks.

Extracting heat from effluent (manure)

In the Netherlands, almost all fish are grown in recirculation systems. The effluent from the fish farming system is often treated in a clarifier and is warm.

R&R Systems has developed an energy system of floating heat exchangers that can extract heat from the effluent. This heat can, for example, be reused for the heating of breeding tanks via a heat pump. Breeding tanks have a temperature of about 27°C. With this system, the water can be pre-heated to a temperature of 12°C to 15°C, which saves substantially on energy costs.

Have a look at the Koeldek (plus) System to find out more about the cost savings this can achieve for fish farms.

Water in breeding tanks sustainably heated

Combining the Koeldek (plus) System with Power Profit Solar Panels or Energy Collectors generates additional, solar energy, which can be used to heat the water in breeding tanks in a fully sustainable manner.
